MK10 All Metal Hotend Kit - Micro Swiss

Nozzle Size: 0.40mm

This is an all metal hotend upgrade for MK 10 style extruders. The lower portion of the thermal break is made from stainless steel (strong with low thermal conductivity), the upper part is made from aluminum. Aluminum was used for the upper for better thermal conductivity, to carry away any heat from the filament. This all metal hotend will let you print at much higher temperature than possible with original PTFE lined one. Another benefit of the Micro Swiss all metal hotend design is a more consistent melt chamber control. During slow extrusion rate, in PTFE lined hotend, transition zone from solid to molten plastic tends to creep upward creating more stringy prints. With all metal design a transition zone is always constant, being located right at the heat break. With fast extrusion rates the PTFE tube doesn't have enough thermal conductivity to properly melt all the plastic passing through. On MK10 extruders this limitation happens around 60 mm/s, depending on nozzle size. The Micro Swiss All metal hotend solves this problem.
